External monitor resolution not compatible with laptop resolution

Hi, I am using Manjaro with i3WM.
I have a ASUS laptop with 1920x1200 screen resolution. I also have an 1920x1080 second monitor.
The issue is: I cannot use the second monitor, cause it’s black and nothing shows on it. Laptop is also useless if the monitor is plugged in. Can you please help me?
